Abstract Animals rely on nervous systems to cope with environmental variability, whereas plants are characterized by lack of nervous system but still have evolved systemic communication systems through signaling molecules that trigger long-distance defense signaling events when encountered with environmental challenges

When antibiotics cause minor irritations or "micro-holes" in the intestinal lining, proline provides the structural integrity needed to patch those areas up

This is based on the observation of lack of similar increase in plasma glutathione levels after the administration of the constituent amino acids of glutathione when compared to the administration of glutathione capsules
